So far, my best VLF DX is 4.7 km with QRSS and 2 km on CW and 1 km with a portable home brew CW RX and PA0RDT miniwhip.

Altogether a very disappointing day, but this was my first field test in over 18 months. More details and photos on my blog at

I am sure there will be a good explanation for these results.

After the tests I was exhausted. In the past this test would have been
trivial. Value good health, as you do not know what is around the corner!
